How to install a cable glue-filled joint box

Installing a glue-filled cable joint box involves preparing the cables, making secure connections, pouring mixed resin, and allowing it to cure for a waterproof, insulated, and mechanically protected joint.

Step-by-Step Installation

1. Prepare the Cable

• Strip the outer sheath of the cable at the connection point, ensuring the exposed length is slightly shorter than the power distribution terminal block to fit properly .
• Clean the exposed conductors to remove any dirt or oxidation. 2. Choose the Connection Method
• Decide whether you need a branch or docking connection.
• Use an insulation piercing wire clamp, such as the Shanghai Kang HK type, for secure electrical contact . 3. Protect the Cable Ends
• Wrap a sponge strip around the ends of the cables to prevent resin leakage and ensure proper sealing inside the joint box . 4. Mix the Resin
• Combine resin components A and B in the recommended proportion.
• Stir thoroughly to ensure a uniform mixture .
• Work quickly, as the resin can thicken or solidify if delayed. 5. Pour the Resin
• Immediately pour the mixed resin into the DIN rail power distribution block or the glue-filled joint box .
• Ensure the resin fully covers all connection points for complete insulation and waterproofing. 6. Allow Curing
• The curing time depends on temperature; at room temperature, it typically takes about one hour .
• Avoid disturbing the box during this period to ensure proper solidification. 7. Safety Precautions
• Wear gloves to prevent skin contact with the resin.
• Ensure good ventilation at the installation site.
• Avoid contact with eyes; rinse immediately with water and seek medical attention if resin enters the eyes .
• Store unfilled resin in a cool, ventilated area away from sunlight and reactive chemicals. 8. Final Steps
• Once cured, check that the box is fully sealed and mechanically stable.
• Dispose of any leftover resin and installation waste properly .

Key Considerations

• Glue-filled joint boxes are suitable for underground or outdoor installations due to their waterproof, moisture-proof, and impact-resistant properties .
• Ensure the box size accommodates all conductors, splices, and fittings.
• Proper installation ensures long-term reliability, preventing water ingress, corrosion, and electrical faults. Following these steps will provide a secure, insulated, and durable cable joint suitable for low-voltage power, communication, or signal applications .
